Test Data for Challenge 2013 Posted
2 April 2013 19:00:00 EDT
The open test set B (100 one-minute noninvasive fetal ECG recordings)
for Challenge 2013 is now available, together with a supplement of 50
additional recordings in training set A.
PhysioNet/Computing in Cardiology Challenge 2013 Opens
21 February 2013 14:00:00 EST
This year's challenge invites participants to develop software capable
of detecting fetal QRS complexes in multichannel noninvasive ECG
recordings, making accurate estimates of fetal heart rate, RR
intervals, and QT intervals. An annotated training set of 25
one-minute recordings is available now; a sample entry, software for
scoring, and test recordings will be available shortly.
First Open Access to a Large Subset of the MIMIC II Clinical Database
4 October 2012 21:00:00 EDT
Open access is now available for the first time to a set of 4000 patient
records included in the MIMIC II Clinical Database
Demo, a downloadable disk image that can be run within a virtual machine or
from a bootable USB flash drive or DVD. Since all of the required software,
including the operating system, is pre-installed and configured, the demo is an
ideal way to begin exploring the MIMIC II Clinical
Database (currently including more than 32,000 patient records) on a spare
PC or Intel Mac with an absolute minimum of setup time.
